Like in topic title . Is there possibility to drive Handle Parameters using some ch() ?


Thanks in advance

I'm not sure I understand. When you bind a handle parameter to a node parameter, that's already in effect a “ch()” type operation.

hey edward,

When you modify polygon with transformSOP(rotate,scale etc.) when you place second transform it's handle is not oriented to selection. But if you RMB on handle and in handle parameters rotate you place rotation information from first transformSOP you get oriented handle to selection.

I found it to be useful couple of times to have this possibility but you can't place expressions in those fields (actually you can but they will be ignored and, as soon as you close it, Houdini will reset it to zero).

I think those parameters should be exposed on transformSOPs. You could apply auto orientation this way.
